To allwzomit may concern! Be it knownthat we, WALTER G-.j B'Laox and AUGUST L. Situationen-citizens ofthe United States, residing al?v B re'a,` the `county of Orange and State of" California,

. have invented certain-new andiu sefulmlmeV provements in Deep- Well Pumps,; ofwhich the following is a specificationsV ,fe-

This invention'relates lto deep well pumps and the object of the invention-is to" provide novel means whereby thejp'mp will be firmly supported within the-tubin while in use and may be withdrawn from t e well without necessitating adismantling orwith-V drawing of the"tubing.f @ther incidental objects of the invention will appear as the description of the saineproceeds. i

' The invention is illustrated in-'theY accompanying` drawings and its novelfeatures 2o will ybe particularly pointed out in the claims following the detalle-d description. l Inl the drawings just mentioned: Y

Fig. 2 is-a view showing-the' plu'ngersa'nd cage with 'the connection between' the plunger and the sucker rods in =elevation and the pump barreLthe tubing and 4the casing 80 in section. Referring more particularly to vthe 'drawings, the. numeral l'designateslthe Well cas ing and the numerals 2 andati` indicate re spectively the upper'and lowei-.sections of t e tubing, while 4 indicg'agte's lthe'pulnp bar- 'relf4 In carrying out thggtlipresent "invention, the upperad lower sections of the tubing are connected byA a coupling' sleeve'f having its ends il'i'ternally threaded or otherwise 40 constructed to be securely but removably connected to the adjacent ends of the sections of the tubing. The inner wall or bore of thiscouplingV sleeve is ared or beveled as indicated at 6, to provide a seat fox-,an anchoring block which 'will Vbe resently more particularly described. Be ow this flared Or-beveled scatG, the lower 4end of the sleeve is flared downwardly and outwardly, as shown'at 7, so

the springs 48 secured tothe shoe 9 'and also Atocau'se contraction' of said springs when the "pump barrel is being withdrawn.l 'The pump barrel 4 is connected by acoupling 10 at its lower end to'the-shoe--g andthe said shoo'is provided with longitudinal grooves loo which receive 1eafllin ih outer sur! barrel.

its eliternal surface as vto perniitfexpaznsion .of

springs 8, the lower ends off-the said springs ,eing secured rigdly in lthe lower ends of he grooveswhilo the upper ends of `the springs play freefy in the grooves as will be readily understood. The coupling 10 car- 'ries a cage 12 in which ,plays aballfvalve 'to control thc'iulet of thc Huid to thepump w The upper end of the pump barrel is secured by threads, or anyother preferred means, in the lo er endof the anchorin block 1B which is adapted vto in an bind upon 4the beveled or ia'red portion 6 of the coupling sleeve 5. This anchoring block is tubular, as shown clearlyin Fig. 2, and is tape-red, as shown atk 14., :it an angle corresponding to the angle of -thc flared portion 6 o tl i e .coupling sleeve. An annular groovev 15.' is Vformed inthe' externalfsurface. ont he anchoring block soas to reduce the contacting suraceof the same and thereby minimize theqfrictional wear. An extended nipple' 16 is'securedtoand risesrfrom the upf er end of the. anchoring block and this ni] P19 has. a' reinforce/dor thickened head 17 at its upper extremity whereby the external andinternal shoulders 18 andjli) respectively are formed. Openings 20 are formed through the-upper portion of the anchoring` block' to permit the escape of the uid 1 tof the'space within the tubing the mouth understood. i y I The plungerV 21 of the pumpiits snugly withinthe pum .pari-el, t is free to reciprocatethereinaid is lloxg or tubular topermit the flow if-liquid: Theupp'r end of `theplunger carfies 'a cage'122- in which is a ball or'otherform of valve 23y and the upper end of the cage is secured to a spider 24 carried by the lower 'end'of the plunger rod 25. The said plunger-rod .extends ,lipwardly from the rppor end ofthef pump barrel andthrough the anchoring block 13 and passes through vlan opening 26 in lthe upper end of. the nipple 16 so-as to-be seclired to a headblock or -lv ammerwQT which isco'nnected to the I o'war ends of the Sucker and around the nipple to pass to of the well, as .will Vbe readily any luid which may be within the pump barrel 'will then be caused lto throu rh the plunger anden the ui stroke of tie plunger said fluid will be li ted so as to pass through the o` enings 2U and thence rise through the tu ing, as will be readily understood. On the up stroke of the plunger, a partial vacuum will be formed below the plunger and above the cage 12 so that the valve in said .cage will be unseated and an additional charge of liquid will then flow through the shoe and the cage into the pump barrel. y

Ii setting up a pump embodying our im,

prove'ments, the coupling sleeve 5 is conf nected to the lowest sections 2 4and 3 of the tubing and the tubing is then lowered into the well in the usual manner. The pump is then assembled and connected with the sucker rods and is lowered through the tubing until the anchoring block 13 enters and operate engages the co'uplingsleeve 5 which constitutes a. seat for said anchoring block. The external diameter' of the pump barrel should be such that it will i`ea,lil v pass through the restricted bore of the anchoringr block and thc spriri'gs 8 will, ol. coul-se, bc contracted and lie 'within the. grooves ll as the shoe passes through said bore. As soon as the shoe emerges from the lower end of the bore, the s'aid springs will. expand and bear against the inner wall of the tubing so as to properly position -the shoe and the pump barrelA and hold the same. steady at all times. After the anchoring block reaches the seat or coupling Sleeve 5, the walking beam, bv which the pumpv is operated, is adjusted ,so that thc ,stroke of the same will cause the head or hammer 27 to 40 strike upon the shoulder 18, the head 17 thus serving as an anvilto receive the blows of the hammer anddrive the anchoring block to its seat. The repeated blows`of the hammer will cause the anchoring block to wedge .within ils scat so that. it will be irmlyvheld thereon by its frictional, engagement therewith. After the anchoring block has been fully seated, the walking beam is adjusted 'that the stroke ot' the same will stop the hammer short of,L the anvil or shoulder 18 and the. i'eeiproc'a'tion of. the sucker rods will i then merely effecty the usual reciprocation of the pump plungervand will lift the fl-uid fromA the Well in vthe ordinary manner. Should the pump become worn so as lo not properly, or" should some accident happen which renders the pump inoperative, il. may be withdrawn withoutdisturbing the tubing so thatthe necessary repairs may be readily made. To withdraw the pump from the well, the walking beam is adjusted so that its stroke'will cause the spider 4 to impinge against the lower shoulder 19 of the head or anvil 17 and vthis jarring action is repeated until the anchoring block .ends ot' the springs S will iinpinge. against the lower beveled surface T of the coupling sleeve or scat. 5 and willV bc thereby con tracted so that they will -i'eadilypass through the bore of said sli-cve.

Uur device is obviously simple in the construction and arrangement ot' its parts and ma)v be readily applied to an)Y well tubing at a slight expense. The anchoring block will. seatV lirinly and securely upon the sleeve 5 so that leakage of the lluid which would prevent economical operation of pump will groove 15 may be fitted with packing .so as to still further gua'd against leakage, but ordinarily we have found lhe use of such packing uni'iecessary;

Having thus described what is claimed as new is:

1. ln a deep well pump. llic combination willi tubing, and ::.eve -iitted iii thc tubini.r and having,r an internal conical bore forming a seal, of a pump barrel adapted to pass through said seat, a tapered anchor block secured on the pump barrel and adapted to engage said seat, an anvil connected with and disposed above said anchor block, a
